Achieving professional certification as a genealogist requires a structured two-part approach: formal training and final credentialing. Aspiring professionals typically build expertise through intensive workshops or university certificates, while joining peer-led study groups is highly effective for mastering the complex portfolio requirements. Final certification is then earned through established organizations like the BCG or ICAPGen, which assess your research proficiency and reporting skills.
1Board for Certification of Genealogists (BCG)The BCG is a leading credentialing body that awards the Certified Genealogist credential. It is best used for validating your professional standards, research proficiency, and technical reporting skills.84%

Pass the Multi-Part Written Exams: Complete proctored evaluations testing your paleography, document transcription/translation, regional history/record knowledge, and a timed 4-hour final research/writing simulation.
Are you leaning toward a geographic specialization (like a specific country or U.S. region) via ICAPGen, or a methodology-based focus via the BCG? I can share study group recommendations or specific prep materials for whichever path you prefer.
The Certified Genealogist® (CG®) credential from Board for Certification of Genealogists is probably the route to investigate first if you want a broadly applicable professional credential.
BCG evaluates an applicant's actual work, rather than simply testing coursework. The current research portfolio includes:
Document work
A research report prepared for another person
A case study involving conflicting, indirect, or negative evidence
A kinship-determination project
Development activities and an ethics commitment
The work is evaluated against formal genealogical standards and the Genealogical Proof Standard. Certification must be renewed every five years.
A good preparation strategy: don't rush to submit the portfolio. Spend substantial time learning source analysis, citation, evidence correlation, research planning, and proof writing; then create practice projects and compare your work against BCG's published rubrics.
2. The ICAPGen Accredited Genealogist® credential
International Commission for the Accreditation of Professional Genealogists offers the Accredited Genealogist® (AG®) credential, which is particularly useful if you want to establish expertise in a specific geographic region.
The process involves:
Selecting an accreditation region.
Completing a four-generation research project.
Taking written examinations.
Completing an oral review.
ICAPGen recommends at least 1,000 hours of research experience and education, including at least 500 hours in your chosen region, before testing. The Four Generation Project specifically evaluates research planning, evidence analysis, conclusions, and client-oriented reporting.
Rather than one being universally "better," consider what you want your credential to demonstrate:
If your goal is...
Consider
General professional genealogy/research
BCG – CG
Demonstrating mastery of a particular geographic area
ICAPGen – AG
Producing client research reports and proof arguments
BCG – CG
Building deep regional expertise
ICAPGen – AG
Eventually holding multiple credentials
You can pursue both
For someone starting from scratch, I'd generally structure the journey like this:
Learn → practice → specialize → get feedback → build professional-quality work → apply.
Don't view a genealogy certificate from a university or institute as equivalent to professional certification. BCG explicitly distinguishes educational certificates—which demonstrate completion of coursework—from professional certification, which evaluates demonstrated competence.
If you tell me your current genealogy experience, the geographic areas you research, and whether you want to do genealogy professionally for paying clients, I can lay out a realistic 1–3 year certification roadmap, including training, books/courses, portfolio preparation, and approximate costs.
If you mean professional credentialing in the U.S., the two main nationally recognized paths are Board for Certification of Genealogists (BCG) and International Commission for the Accreditation of Professional Genealogists (ICAPGen). The National Genealogical Society identifies these as the two organizations that credential professional genealogists.
The most practical path
For most genealogists who want a broadly applicable professional credential, I'd structure the process like this:
Build a strong research foundation.
Become comfortable with source analysis, evidence correlation, citation, research planning, and the Genealogical Proof Standard (GPS). BCG's GPS consists of reasonably exhaustive research, complete and accurate citations, analysis/correlation, resolution of conflicting evidence, and a sound written conclusion.
Get substantial hands-on research experience.
Don't rush into certification immediately. Produce research reports, proof arguments, client-style work, and case studies. Ideally, have experienced genealogists critique your work.
Take advanced education strategically.
Institutes and programs such as ProGen, GRIP, SLIG, IGHR, and Gen-Fed can be particularly useful. BCG specifically notes that applicants who undertake intensive education such as institutes or ProGen have had higher success rates, although none is mandatory.
Study the certification requirements before creating your portfolio.
This is crucial. Don't simply accumulate certificates and assume you're ready. BCG evaluates your actual genealogical work, not merely your coursework.
Apply to BCG if you want the Certified Genealogist® (CG) credential.
Under the current 2025 guide, the research portfolio includes a Genealogist's Code, development activities, document work, a research report prepared for another person, a case study involving conflicting/indirect/negative evidence, and a kinship-determination project. The application is now a two-part portfolio process.
Alternatively, consider ICAPGen if regional specialization is central to your work.
ICAPGen's Accredited Genealogist® (AG®) credential is organized around geographical regions and evaluates both regional knowledge and practical research ability. Its process includes testing and an oral review.

Renewal
Every 5 years
BCG's current fees are $80 for the preliminary application, $200 for each of the two portfolio parts, $80 annually for maintenance, and $300 for renewal every five years. Board for Certification of Genealogists ICAPGen likewise requires renewal every five years, including continuing research/education participation and other requirements.
One important distinction: a genealogy course certificate isn't the same thing as professional certification. For example, NGS explicitly says completion of its advanced-skills course does not make someone a certified genealogist; formal credentials come through organizations such as BCG or ICAPGen.
If you're starting from scratch, I'd spend roughly 1–3 years developing research skills and a portfolio before applying rather than treating certification as a short course. The credential is ultimately evidence that you can consistently produce professional-quality genealogical work.
If you tell me your current experience level (beginner/intermediate/advanced), your main geographic specialties, and whether you want to do client research professionally, I can lay out a concrete 12-, 18-, or 24-month certification roadmap.
Attend multi-week immersive programs like the Institute of Genealogy and Historical Research (IGHR), Salt Lake Institute of Genealogy (SLIG) , or the GRIP Genealogy Institute.
The ICAPGen Path (Accredited Genealogist - AG): Focuses heavily on a specific geographic or cultural regional specialization (e.g., specific U.S. regions, Ireland, Scandinavia). It requires a four-generation research project followed by rigorous proctored written and practical exams testing paleography, local history, record types, and a timed research simulation.[](]()](]()]()
Step 4: Submit and Persevere Through Evaluation
Prepare your materials meticulously—eliminating assumptions, double-checking citations, and ensuring original analysis.
Are you leaning toward a geographic specialization (which fits ICAPGen well) or a general portfolio/kinship approach (which fits BCG)? Let me know, and I can help you find the right study groups or institutes to target.
Prepare a portfolio demonstrating client-ready work. This includes a self-evaluation, a multi-generation lineage research report, a detailed proof argument/case study, and document transcripts/abstracts.
Best for: Researchers who possess encyclopedic knowledge of a specific geographic region (e.g., specific U.S. states/regions, Germany, Scandinavia, British Isles) and its unique record groups. [](https://www.legacytree.com/blog/genealogy-organizations)
Master the Standards: No matter which path you choose, make sure you thoroughly study Genealogy Standards (published by BCG), as both boards judge work based on industry-accepted baselines of citation and analysis. [](https://www.bcgcertification.org/)
Join a Study Group: Many candidates join peer-led or formal study groups (often coordinated through organizations like the Association of Professional Genealogists ) to critique draft research reports before final submission.
Build a Portfolio First: Do not rush the application. Spend months (or years) ensuring your everyday research reports meet absolute professional standards before paying submission fees.
Are you leaning toward a geographic specialty (which fits ICAPGen well) or a general methodology/writing portfolio (which fits BCG)? If you share your area of focus, I can help point you toward specific study resources.
Build research experience and education in evidence analysis, source citation, methodology, and report writing.
Study the BCG Genealogy Standards and practice producing client-quality work.
Apply for the CG portfolio process, which evaluates your research, writing, analysis, and adherence to professional standards.
If you specialize in a particular geographic region, consider Accredited Genealogist® (AG®) through International Commission for the Accreditation of Professional Genealogists. ICAPGen recommends roughly 1,000 hours of combined research and education, including 500+ hours in your chosen region.
For most aspiring professional genealogists, CG is the stronger general-purpose starting credential; AG is particularly useful for regional specialization.

Which one is best?
For a broadly recognized professional credential, I'd lean toward BCG's CG credential. It is designed around demonstrating competence through a portfolio of actual genealogical work.
ICAPGen's AG is especially attractive if you want to specialize geographically. You choose an accreditation region and demonstrate substantial expertise in its records, history, geography, methodology, and language.
A practical path is:
Build substantial research experience. Don't rush into credentialing before you're comfortable with original records, indirect evidence, conflicting evidence, source analysis, and negative searches.
Get serious genealogical education. Institutes, conferences, university/certificate programs, and self-directed study can all help. Formal academic training isn't necessarily required for ICAPGen.
Choose a specialization. For ICAPGen, for example, you need a geographic region and significant experience researching it.
Start keeping professional-quality research logs and citations now. This is one of the biggest differences between casual family-history research and professional genealogy.
Practice producing client-ready reports. Your ability to explain why a conclusion is justified is at least as important as finding records.
Then enter the credentialing process.
For ICAPGen specifically, applicants normally need at least 1,000 hours of combined genealogical research and education, with more than 500 hours expected in the chosen region. The process then includes a four-generation project and written/oral testing.
The four-generation project is substantial: it requires connecting four generations, analyzing evidence, documenting sources, maintaining a research log, and presenting the results as though to a client.
My recommendation
If you're starting from scratch, I'd spend the first year or two building skills and a portfolio rather than immediately pursuing a credential. Once you have a strong research specialty, decide between:
CG → strongest fit if you want to demonstrate general professional genealogical competence.
AG → excellent if you want to market yourself as an expert in a particular geographic region.
Both → potentially worthwhile later if genealogy becomes a serious long-term profession.
If you tell me your current level (beginner/intermediate/experienced), the geographic areas you research, and whether you want to do genealogy as a business, I can lay out a step-by-step 1–3 year certification plan, including education, estimated costs, and what to work on first.
If you're starting from scratch, I'd spend the first year or two building skills and a portfolio rather than immediately pursuing a credential. Once you have a strong research specialty, decide between:
Join a Study Group: Do not try to do it alone. Peer study groups specifically organized for BCG or ICAPGen candidates offer invaluable line-by-line critique of source citations and proof arguments.
Are you leaning toward a specific geographic region or specialized skill set (like genetic genealogy ), and do you prefer comprehensive portfolios over proctored exams ? I can help you choose which organization fits your background best.
Certified Genealogist® (CG® — BCG): Best choice if you want to demonstrate broad professional competence in genealogical research, analysis, and reporting. You apply by submitting a portfolio that demonstrates your ability to meet genealogy standards. The process begins with a preliminary application and culminates in evaluation of the portfolio.
Accredited Genealogist® (AG® — ICAPGen): Particularly attractive if you want to specialize geographically. You choose a region and demonstrate substantial regional expertise through a four-generation project, written examinations, and an oral review. ICAPGen recommends at least 1,000 hours of combined research experience and education, including at least 500 hours in your chosen region, before applying.
My recommendation
For someone starting toward a professional career, I'd generally work toward the CG credential first, unless you already have deep expertise in a particular geographic region. The CG process forces you to develop the skills clients and other genealogists care about: sound research methodology, source analysis, proof arguments, written conclusions, and professional standards.
A practical path is:
Build your research foundation — records, repositories, source citations, evidence analysis, research planning, and the Genealogy Standards.
Get substantial hands-on experience with difficult research problems rather than only researching your own family.
Study successful professional work and obtain feedback from experienced genealogists.
Start assembling work suitable for a BCG portfolio. Don't wait until you're ready to apply; deliberately create projects that exercise the required skills.
Apply to BCG and complete the portfolio. The current BCG process requires a preliminary application followed by a final application and portfolio evaluation.
Maintain the credential and continue professional development after certification.
If your goal is to become a paid professional genealogist, rather than simply earn a credential, I can also lay out a 12–24 month roadmap to becoming a certified genealogist, including what courses to take, books to study, how to practice, and approximately what the certification process will cost.
